2.2.5.11 ATX Connector

operating system. Your system will enter the “soft power off ” state.
To power on your system automatically, enable “Resume On
Alarm” in the Power Management Setup of the Award BIOS. This
will allow you to set the date and time you would like your
system to power-on. Install the 20-pin ATX power cable
connector into location PL1 on the system board. The 20-pin
connector can be inserted into PL1 only if pin 1 of the connector
is aligned with pin 1 of PL1. The location of PL1 is shown on the
